Chapter 4: Economic Efficiency, Government Price Setting, and Taxes Consumer Surplus and Producer Surplus Consumer Surplus FIGURE 4-1 Deriving the Demand Curve for Chai Tea With four consumers in the market for chai tea, the demand curve is determined by the highest price each consumer is willing to pay. For prices above $6, no tea is sold because $6 is the highest price any consumer is willing to pay. For prices of $3 and below, every one of the four consumers is willing to buy a cup of tea. Distinguish between the concepts of consumer surplus and producer surplus. 4.1 LEARNING OBJECTIVE

8 8 of 38 Copyright © 2010 Pearson Education, Inc. Publishing as Prentice Hall · Economics · R. Glenn Hubbard, Anthony Patrick OBrien, 3e. Chapter 4: Economic Efficiency, Government Price Setting, and Taxes Consumer Surplus and Producer Surplus Consumer Surplus FIGURE 4-2 Measuring Consumer Surplus Panel (a) shows the consumer surplus for Theresa, Tom, and Terri when the price of tea is $3.50 per cup. Theresas consumer surplus is equal to the area of rectangle A and is the difference between the highest price she would pay$6and the market price of $3.50. Toms consumer surplus is equal to the area of rectangle B, and Terris consumer surplus is equal to the area of rectangle C Total consumer surplus in this market is equal to the sum of the areas of rectangles A, B, and C, or the total area below the demand curve and above the market price. In panel (b), consumer surplus increases by the shaded area as the market price declines from $3.50 to $3.00. Distinguish between the concepts of consumer surplus and producer surplus. 4.1 LEARNING OBJECTIVE

Chapter 4: Economic Efficiency, Government Price Setting, and Taxes Consumer Surplus and Producer Surplus Consumer Surplus FIGURE 4-3 Total Consumer Surplus in the Market for Chai Tea The demand curve tells us that most buyers of chai tea would have been willing to pay more than the market price of $2.00. For each buyer, consumer surplus is equal to the difference between the highest price he or she is willing to pay and the market price actually paid. Therefore, the total amount of consumer surplus in the market for chai tea is equal to the area below the demand curve and above the market price. Consumer surplus represents the benefit to consumers in excess of the price they paid to purchase the product. Distinguish between the concepts of consumer surplus and producer surplus. 4.1 LEARNING OBJECTIVE

10 10 of 38 Copyright © 2010 Pearson Education, Inc. Publishing as Prentice Hall · Economics · R. Glenn Hubbard, Anthony Patrick OBrien, 3e. Chapter 4: Economic Efficiency, Government Price Setting, and Taxes Consumer surplus allows us to measure the benefit consumers receive in excess of the price they paid to purchase a product. This figure shows the consumer surplus that households receive from subscribing to broadband Internet service, which is estimated to be $890.5 million per month. The Consumer Surplus from Broadband Internet Service Making the Connection YOUR TURN: Test your understanding by doing related problem 1.8 at the end of this chapter. Distinguish between the concepts of consumer surplus and producer surplus. 4.1 LEARNING OBJECTIVE

Chapter 4: Economic Efficiency, Government Price Setting, and Taxes Consumer Surplus and Producer Surplus Producer Surplus FIGURE 4-4 Measuring Producer Surplus Panel (a) shows Heavenly Teas producer surplus. Producer surplus is the difference between the lowest price a firm would be willing to accept and the price it actually receives. The lowest price Heavenly Tea is willing to accept to supply a cup of tea is equal to its marginal cost of producing that cup. When the market price of tea is $1.75, Heavenly receives producer surplus of $0.75 on the first cup (the area of rectangle A), $0.50 on the second cup (rectangle B), and $0.25 on the third cup (rectangle C). In panel (b), total producer surplus is equal to the area above the supply curve and below the market price, shown in red. Distinguish between the concepts of consumer surplus and producer surplus. 4.1 LEARNING OBJECTIVE

13 13 of 38 Copyright © 2010 Pearson Education, Inc. Publishing as Prentice Hall · Economics · R. Glenn Hubbard, Anthony Patrick OBrien, 3e. Chapter 4: Economic Efficiency, Government Price Setting, and Taxes Consumer Surplus and Producer Surplus What Consumer Surplus and Producer Surplus Measure Consumer surplus measures the net benefit to consumers from participating in a market rather than the total benefit. Consumer surplus in a market is equal to the total benefit received by consumers minus the total amount they must pay to buy the good or service. Similarly, producer surplus measures the net benefit received by producers from participating in a market. Producer surplus in a market is equal to the total amount firms receive from consumers minus the cost of producing the good or service. Distinguish between the concepts of consumer surplus and producer surplus. 4.1 LEARNING OBJECTIVE

14 14 of 38 Copyright © 2010 Pearson Education, Inc. Publishing as Prentice Hall · Economics · R. Glenn Hubbard, Anthony Patrick OBrien, 3e. Chapter 4: Economic Efficiency, Government Price Setting, and Taxes The Efficiency of Competitive Markets Marginal Benefit Equals Marginal Cost in Competitive Equilibrium Understand the concept of economic efficiency. 4.2 LEARNING OBJECTIVE FIGURE 4-5 Marginal Benefit Equals Marginal Cost Only at Competitive Equilibrium In a competitive market, equilibrium occurs at a quantity of 15,000 cups and a price of $2.00 per cup, where marginal benefit equals marginal cost. This is the economically efficient level of output because every cup has been produced where the marginal benefit to buyers is greater than or equal to the marginal cost to producers.

17 17 of 38 Copyright © 2010 Pearson Education, Inc. Publishing as Prentice Hall · Economics · R. Glenn Hubbard, Anthony Patrick OBrien, 3e. Chapter 4: Economic Efficiency, Government Price Setting, and Taxes The Efficiency of Competitive Markets Deadweight Loss FIGURE 4-7 When a Market Is Not in Equilibrium, There Is a Deadweight Loss Economic surplus is maximized when a market is in competitive equilibrium. When a market is not in equilibrium, there is a deadweight loss. When the price of chai tea is $2.20, instead of $2.00, consumer surplus declines from an amount equal to the sum of areas A, B, and C to just area A. Producer surplus increases from the sum of areas D and E to the sum of areas B and D. At competitive equilibrium, there is no deadweight loss. At a price of $2.20, there is a deadweight loss equal to the sum of areas C and E. Understand the concept of economic efficiency. 4.2 LEARNING OBJECTIVE

Chapter 4: Economic Efficiency, Government Price Setting, and Taxes The Efficiency of Competitive Markets Economic Surplus and Economic Efficiency Economic efficiency A market outcome in which the marginal benefit to consumers of the last unit produced is equal to its marginal cost of production and in which the sum of consumer surplus and producer surplus is at a maximum. Understand the concept of economic efficiency. 4.2 LEARNING OBJECTIVE

19 19 of 38 Copyright © 2010 Pearson Education, Inc. Publishing as Prentice Hall · Economics · R. Glenn Hubbard, Anthony Patrick OBrien, 3e. Chapter 4: Economic Efficiency, Government Price Setting, and Taxes Government Intervention in the Market: Price Floors and Price Ceilings Price Floors: Government Policy in Agricultural Markets FIGURE 4-8 The Economic Effect of a Price Floor in the Wheat Market If wheat farmers convince the government to impose a price floor of $3.50 per bushel, the amount of wheat sold will fall from 2.0 billion bushels per year to 1.8 billion. If we assume that farmers produce 1.8 billion bushels, producer surplus then increases by the red rectangle Awhich is transferred from consumer surplusand falls by the yellow triangle C. Consumer surplus declines by the red rectangle A plus the yellow triangle B. There is a deadweight loss equal to the yellow triangles B and C, representing the decline in economic efficiency due to the price floor. In reality, a price floor of $3.50 per bushel will cause farmers to expand their production from 2.0 billion to 2.2 billion bushels, resulting in a surplus of wheat. Explain the economic effect of government-imposed price floors and price ceilings. 4.3 LEARNING OBJECTIVE

Chapter 4: Economic Efficiency, Government Price Setting, and Taxes Government Intervention in the Market: Price Floors and Price Ceilings Price Ceilings: Government Rent Control Policy in Housing Markets FIGURE 4-9 The Economic Effect of a Rent Ceiling Without rent control, the equilibrium rent is $1,500 per month. At that price, 2,000,000 apartments would be rented. If the government imposes a rent ceiling of $1,000, the quantity of apartments supplied falls to 1,900,000, and the quantity of apartments demanded increases to 2,100,000, resulting in a shortage of 200,000 apartments. Producer surplus equal to the area of the blue rectangle A is transferred from landlords to renters, and there is a deadweight loss equal to the areas of yellow triangles B and C.

Chapter 4: Economic Efficiency, Government Price Setting, and Taxes Government Intervention in the Market: Price Floors and Price Ceilings Positive and Normative Analysis of Price Ceilings and Price Floors Whether rent controls or federal farm programs are desirable or undesirable is a normative question. Whether the gains to the winners more than make up for the losses to the losers and for the decline in economic efficiency is a matter of judgment and not strictly an economic question. Explain the economic effect of government-imposed price floors and price ceilings. 4.3 LEARNING OBJECTIVE

27 27 of 38 Copyright © 2010 Pearson Education, Inc. Publishing as Prentice Hall · Economics · R. Glenn Hubbard, Anthony Patrick OBrien, 3e. Chapter 4: Economic Efficiency, Government Price Setting, and Taxes The Economic Impact of Taxes Analyze the economic impact of taxes. 4.4 LEARNING OBJECTIVE The Effect of Taxes on Economic Efficiency FIGURE 4-10 The Effect of a Tax on the Market for Cigarettes Without the tax, market equilibrium occurs at point A. A $1.00-per-pack tax on cigarettes will cause the supply curve for cigarettes to shift up by $1.00, from S 1 to S 2. The new equilibrium occurs at point B. The price of cigarettes will increase by $0.90, to $4.90 per pack, and the quantity sold will fall to 3.7 billion packs. The tax on cigarettes has increased the price paid by consumers from $4.00 to $4.90 per pack. Producers receive a price of $4.90 per pack (point B), but after paying the $1.00 tax, they are left with $3.90 (point C). The government will receive tax revenue equal to the green shaded box. Some consumer surplus and some producer surplus will become tax revenue for the government and some will become deadweight loss, shown by the yellow-shaded area.

29 29 of 38 Copyright © 2010 Pearson Education, Inc. Publishing as Prentice Hall · Economics · R. Glenn Hubbard, Anthony Patrick OBrien, 3e. Chapter 4: Economic Efficiency, Government Price Setting, and Taxes The Economic Impact of Taxes Tax Incidence: Who Actually Pays a Tax? Determining Tax Incidence on a Demand and Supply Graph FIGURE 4-11 The Incidence of a Tax on Gasoline With no tax on gasoline, the price would be $3.00 per gallon, and 144 billion gallons of gasoline would be sold each year. A 10-cents-per-gallon excise tax shifts up the supply curve from S 1 to S 2, raises the price consumers pay from $3.00 to $3.08, and lowers the price sellers receive from $3.00 to $2.98. Therefore, consumers pay 8 cents of the 10-cents-per-gallon tax on gasoline, and sellers pay 2 cents. Analyze the economic impact of taxes. 4.4 LEARNING OBJECTIVE

31 31 of 38 Copyright © 2010 Pearson Education, Inc. Publishing as Prentice Hall · Economics · R. Glenn Hubbard, Anthony Patrick OBrien, 3e. Chapter 4: Economic Efficiency, Government Price Setting, and Taxes The Economic Impact of Taxes Tax Incidence: Who Actually Pays a Tax? Does It Matter Whether the Government Collects a Tax from Buyers or Sellers? FIGURE 4-12 The Incidence of a Tax on Gasoline Paid by Buyers With no tax on gasoline, the demand curve is D 1. If a 10-cents-per-gallon tax is imposed that consumers are responsible for paying, the demand curve shifts down by the amount of the tax, from D 1 to D 2. In the new equilibrium, consumers pay a price of $3.08 per gallon, including the tax. Producers receive $2.98 per gallon. This is the same result we saw when producers were responsible for paying the tax. Analyze the economic impact of taxes. 4.4 LEARNING OBJECTIVE

Chapter 4: Economic Efficiency, Government Price Setting, and Taxes Appendix Quantitative Demand and Supply Analysis Use quantitative demand and supply analysis. LEARNING OBJECTIVE Demand and Supply Equations FIGURE 4A-1 Graphing Supply and Demand Equations After statistically estimating supply and demand equations, we can use the equations to draw supply and demand curves. In this case, the equilibrium rent for apartments is $1,500 per month, and the equilibrium quantity of apartments rented is 1,500,000. The supply equation tells us that at a rent of $346, the quantity of apartments supplied will be zero. The demand equation tells us that at a rent of $3,000, the quantity of apartments demanded will be zero. The areas representing consumer surplus and producer surplus are also indicated on the graph.

Chapter 4: Economic Efficiency, Government Price Setting, and Taxes Appendix Quantitative Demand and Supply Analysis Calculating Consumer Surplus and Producer Surplus FIGURE 4A-2 Calculating the Economic Effect of Rent Controls Once we have estimated equations for the demand and supply of rental housing, a diagram can guide our numeric estimates of the economic effects of rent control. Consumer surplus falls by an amount equal to the area of the yellow triangle B and increases by an amount equal to the area of the blue rectangle A. The difference between the values of these two areas is $213,750,000. Producer surplus falls by an amount equal to the area of the blue rectangle A plus the area of the yellow triangle C. The value of these two areas is $587,500,000. The remaining producer surplus is equal to the area of triangle D, or $278,000,000. Deadweight loss is equal to the area of triangle B plus the area of triangle C, or $373,750,000. Use quantitative demand and supply analysis. LEARNING OBJECTIVE
